Answer:
See explanation.
Explanation:
Hello,
In this case, for the described chemical reaction:
2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H2O(l)
We can notice there is a 2:1 molar ratio between the moles of hydrochloric acid and magnesium hydroxide, therefore, at the equivalence point:
And in terms of volumes and concentrations we verify:
So we use the given data to proof it:
Therefore, we can conclude the data is wrong by means of the 2:1 mole ratio that for sure was not taken into account. This is also supported by the fact that normalities are actually the same, but the nomality of magnesium hydroxide is the half of the hydrochloric acid normality since the acid is monoprotic and the base has two hydroxyl ions.
Best regards.

Explanation
In a steam turbine electricity generation, the mechanical energy in form of pressure present in steam is extracted and converted into kinetic energy by allowing the steam to flow through the stationary blades. This kinetic energy is transmitted to the moving blades connected to the alternator of a steam turbine generator.
The matching of the process is shown below:

Answer:
25.39
Explanation:
Given parameters:
Abundance of X-25 = 80.5%
Abundance of X - 27 = 19.5%
Unknown:
Average atomic mass of X = ?
Solution:
The average atomic mass of X can be derived using the expression below:
Average atomic mass = (abundance x mass of X - 25) + (abundance x mass of X - 27)
Average atomic mass = (80.5% x 25) + (19.5% x 27) = 25.39
